Steel infrastructure, such as railway and highway bridges, offshore structures and pipelines, is generally subjected to service load and environmental conditions. The deteriorated behavior of aged structures has attracted much attention in civil community.

This Special-Session will share new research results related to sustainable steel structures and will provide a platform for researchers to have in-depth discussions and to enhance future collaboration. It covers the following topics and also other related topics:

  • Retrofitting solutions using novel approaches, e.g., FRP/SMA (e.g., bond behavior, pre-stressing methods, etc.)
  • Long-term behavior under severe environmental exposures and sustained loading (e.g., corrosion, fatigue, etc.)
  • Experimental, numerical and analytical studies on assessments of metallic retrofitting systems
  • Life-cycle analysis, assessment and evaluation of aging steel structures

Infrastructure is subjected to one or more natural hazards, such as earthquakes, hurricanes, landslides and flooding. Effects of multiple hazards have attracted much attention in civil community.

This Special-Session will share new research results on this topic and will provide a platform for researchers to have in-depth discussions and to enhance future collaboration. It covers the following topics and also other related topics:

  • Assessment of coupling effects of multiple hazards (e.g., concurrent hazards, cascading hazards)
  • Assessment of environmental effects (e.g., temperature, humidity, carbon dioxide)
  • Multi-hazard risk assessment and mitigation of infrastructure
  • Improvement of infrastructure resilience subjected to multi-hazards

Traditional masonry and timber structures are subjected to performance degradation due to the natural and human activities induced hazards during their service periods, and thus requires particular attention regarding structural performance monitoring, assessment and rehabilitation.

This Special-Session will share new research results on this topic and will provide a platform for researchers to have in-depth discussions and to enhance future collaboration. It covers but is not limited to the following topics:

  • Structural damages and performance of partially damaged structures
  • Inspection, monitoring and assessment techniques and case studies
  • Fire and seismic resistance testing and modeling
  • Structural performance rehabilitation and strengthening techniques

In the long-term service time, the performance of concrete structures is significantly influenced by the surrounding environmental conditions. The steel corrosion in concrete due to aggressive environment (e.g., chloride ions and carbon dioxide) has been a major concern for the deterioration of concrete structures. Additionally, the environmental actions (e.g., freezing and thawing, and sulfate corrosion) can also directly degrade the mechanical performance of concrete structures. Generally, concrete structures in a service life may experience the following stages: environmental aggressive agent penetration, steel corrosion initiation, crack initiation, crack propagation, concrete spalling and collapse. Therefore, it is essential to investigate the environmental impact on performance of concrete structures. To study the environmental impact on reduction of structural capacity and durability, the experimental methods including field exposure test and laboratory accelerated test, modeling of mechanical and durability behaviors, and numerical simulation at multi-scales have been developed. The aim of this special session is to present the advances in performance evolution of concrete structures in various aggressive environment. The scope of this session includes but is not limited to the experimental study and numerical simulation on the durability-related issues of material deterioration and structural responses under environmental actions.
